What is meant by the term “Great acceleration” in the context of sustainability?

It means the sudden increase in the mean ocean temperature leading to a slow-down of the great inter-ocean circulations causing major losses in biodiversity.

It is the term used for the sudden exponential increase in global human impact observed from the 1950s till today as a result of the switch to a global carbon-based economy.

It is the term used when in the 1970s more and more countries developed their own sustainability agenda and began with its implementation.

A country’s economy is called Green Economy when the main contributions to the GDP come from less polluting economic sectors, so-called green sectors.

Green economy is when a country implements all pollution control and conservation measures to contribute to the global efforts to curb climate change.

What is measured with the Human Development Index (HDI)?

HDI measures a country’s achievements in serving all people with better sanitation, access to water, and better income. It highlights achievements in poverty alleviation and socio-economic inclusion.

HDI measures the area of productive land and water ecosystems required to produce the resources that the population consumes and required to assimilate the wastes that the population produces. The lower the HDI is the better the rating of a country.

HDI measures a country’s average achievements in health, education, knowledge and standard of living. It serves to compare socio-economic development efforts of countries.

What are natural assets?

Natural assets are all naturally growing resources harvested for various uses.

Natural assets are natural resources which have an economic value and are extracted for human consumption or the production of goods.

Natural assets are goods made of bio-degradable materials.

Score: 0

Natural assets are natural resources which have an economic value and are extracted for human consumption or the production of goods.

Why can we not achieve sustainability by implementing strict resources conservation, e.g. by consuming less water?

Because our current resources, such as water are over-committed or will be depleted within our lifetime. Yet many people do not have access to resources to satisfy basic human needs, while Earth’s human population keeps growing potentially and ever more people have to be served.

Because the legal frameworks and political will are lacking in many countries, and a major effort is required to make people aware and enforce environmental rules.

Because a major investment is required in research and development of technologies which would enable us to better preserve our resources. However, research & development is not given adequate priority.

What does an Ecological Footprint of a region that is 83 % above the Biocapacity of the same region mean?

The region can increase its biocapacity to balance its ecological footprint.

The region has exhausted its biocapacity and draws resources from other regions.

Why are so-called “Novel Entities” so relevant in Earth’s ecosystems functioning?

Novel Entities or emerging contaminants are relevant as an increasing, yet little understood, concern because of their long lifetime, toxicity and endocrine properties, and the global occurrence and accumulation in the aquatic environment.

Novel Entities are associations of global earth observation and monitoring systems which are relevant, because changes in environmental parameters are now being easily detected and an automatic alert is sent to the relevant international agencies.

Novel Entities are relevant for ecosystems functioning, because they are essential catalysts in most biological and biochemical processes on Earth and changes in the availability has an impact on biodiversity and contaminant removal.

Score: 0

Novel Entities or emerging contaminants are relevant as an increasing, yet little understood, concern because of their long lifetime, toxicity and endocrine properties, and the global occurrence and accumulation in the aquatic environment.
